The Gunners beat Fenerbahce 3-0 in Istanbul last week, but a cautious Wenger intends to send out a full-strength side to complete qualification.
"It's a very, very important tie for us, because we want to be in the group stage the next day," Wenger said.
"If you want to knock somebody out you need attitude and commitment or you don't do it.
"That demands attitude and commitment and desire to play the game with full power, like we love to do it.
"We want to finish the job. We have a decent advantage, but we want to get over the line."
It will be the Gunners' first return to the Emirates Stadium since a 3-1 defeat to Aston Villa on the opening day of the Barclays Premier League season which provoked the fans' ire.
Supporters expressed frustration over Arsenal's perceived dithering in the transfer market which has seen them miss out on significant signings.
"I still am optimistic and I hope I will not disappoint you," said Wenger, who believes the transfer window should close before the season starts, but recognises Arsenal's need to augment the squad.
"We have not a fixed number (of signings in mind). I just think we are a bit short at the moment.
